Abstract: A base of a detection pipe is fixed. A vibration piece has its one end fixed to a closing portion and the other end provided with a permanent magnet. An electromagnet is closely attached inside the detection pipe such that it is arranged in a direction of axis of the permanent magnet, thereby forming a folded cantilever. Vibration is detected by a distortion detecting element, and the output therefrom is amplified by an amplification circuit for driving the electromagnet. Thus, the detection pipe, closing portion and vibration piece are repeatedly vibrated.

Abstract: A dual tamper evident closure for sealing the neck portion of a container. The closure which is preferably made of one single piece of plastic material, has a body with a skirt sized and shaped to fit onto and be screwed or otherwise detachably fixed to the neck portion. The body also has a top surface with an opening in registry with the outlet of the neck portion. The closure also has a cap that is connected to the closure body by a hinge and is sized and shaped to cover the opening of the body and thus to close the outlet of the neck portion when folded down in a closed position. A tamper evident band in the form of a ring is connected by frangible bridges to the lower edge of the skirt of the body.  This band is provided with hooks designed to cooperate with an annular bead projecting from the neck portion in order to rigidly retain the body onto the neck portion. A tear tab integrally projects from the peripheral edge of the closure cap in a position that is opposite to the hinge. This tear tab has an upper end that is connected by a frangible bridge to the peripheral edge of the closure cap, and a lower end that is rigidly connected to the tamper evident band. In use, the tear tab as long as it remains connected to the closure cap, warrants that the closure cap has not been lifted up and thus the container has not been opened.

Abstract: A stepping motor, head, or other drive mechanism is driven with high precision without using a high speed CPU or dedicated hardware. Timing data controlling the timing at which drive mechanism operation changes, and plural control data controlling drive mechanism operation at each change timing, are stored to memory. After a drive command from the, CPU is received, timing data is read from memory by DMA, and sent to a timer. Based on a time-up signal from the timer, the drive control data is read sequentially from memory by DMA for each of the plural control data types and sent to a drive control unit. After all control data types are sent once, the next timing data is sent to the timer and the operation repeated. The drive control unit drives the drive mechanism based on the control data.
